My First FPGA DesignMay 2007IntroductionWelcome to Altera and the world of programmable logic! This tutorialwill teach you how to create a simple FpGa design and run it on yourdevelopment board. The tutorial takes less than an hour to complete Thefollowing sections provide a quick overview of the design flow, explainwhat you need to get started, and describe what you will learnDesign FlowThe standard FPGa design flow starts with design entry usingschematics or a hardware description language(HDL), such asVerilog hDL or VHDL. In this step, you create the digital circuit that isimplemented inside the FPGA. The flow then proceeds throughcompilation, simulation, and programming and verification in the FPGAhardware(see Figure 1-1Figure 1-1. Design FlowDesignD CompileSimulateProgramardwareVerifyThis tutorial guides you through all of the steps except for simulationAlthough it is not covered in this document, simulation is very importantdesigns There are two types of simulation, RIL and timing. RTL(or reto learn, and there are entire applications devoted to simulating hardwfunctional) simulation allows you to verify that your code ismanipulating the inputs and outputs appropriately Timing(or postplace-and-route) simulation verifies that the design meets timing andfunctions appropriately in the deviceIg See"Next Steps"on page 1-43 for links to further informationabout simulationAltera CorporationIntroductionBefore You beginThis tutorial assumes the following prerequisitesYou generally know what an FPGA is. This tutorial does not explainthe basic concepts of programmable logicYou are somewhat familiar with digital circuit design and electronicdesign automation (eda) toolsYou have installed the Altera Quartus@ Ii software on yourcomputer. If you do not have the Quartus II software, you candownloaditfromtheAlterawebsiteatwww.altera.com/downloadYou have an Altera Cyclone( Ill Starter Board (or equivalent)onwhich you will test your project. Using a development board helpsyou to verify whether your design is really workinYou have gone through the quick start guide and or the gettingstarted user guide for your development kit. These documentsensure that you haveInstalled the required softwaree Determined that the development board functions properly andis connected to your computerInstalled the uSB-BlasterTM driver, which allows you to programthe fpga on the development board with your own designWhat You will learnIn this tutorial, you will perform the following tasksCreate a design that causes leds on the development board to blink at aspeed that is controlled by an input button--This design is easy to createand gives you visual feedback that the design works. Of course, youcan use your Cyclone Ill board to run other designs as well. For theled design, you will write verilog hdl code for a simple 32-bitcounter,add a phase-locked loop(PLl) megafunction as the clocksource, and add a 2-input multiplexer megafunction when thedesign is running on the board, you can press an input switch tomultiplex the counter bits that drive 4 output ledsAltera CorporationMy First FPGA Design TutorialMy First FPGA Designconcepts about Quartus II projects, such as entering a design using aschematic editor and HDL, compiling your design, anddownloading it into the fpga on your development boardDevelop a foundation to learn more about FPGas--For example, you cancreate and download digital signal processing(Dsp)functions ontoa single chip, or build a multi-processor system, or create anythingelse you can imagine all on the same chip You don t have to scourdata books to find the perfect logic device or create your own asicAll you need is your computer, your imagination, and the Cyclone IllStarter boardFor information about Altera training classes(both on-line and inperson), go to the Altera web site at mysupport. altera. com/etraining/orcontact your local Altera sales representativeGet startedYou begin this tutorial by creating a new Quartus ll project. A project is aset of files that maintain information about your fpga design thQuartus II Settings File(. qsf)and Quartus II Project File(. qpf) files are theprimary files in a Quartus ll project. To compile a design or make pinassignments, you must first create a project1. In the Quartus II software, select File> New Project Wizard. TheIntroduction page opens.
